   3  * RecordSet to HTML Table
   4  *
   5  * Convert a recordset to a html table. Multiple tables are generated
   6  * if the number of rows is > $gSQLBlockRows. This is because
   7  * web browsers normally require the whole table to be downloaded
   8  * before it can be rendered, so we break the output into several
   9  * smaller, faster rendering tables.
  10  *
  11  * This file is part of ADOdb, a Database Abstraction Layer library for PHP.
